FRISCO -- The Dallas Cowboys will take one more close look at quarterback Tony Romo's back this week before they make a final decision on whether to carry him on the roster or place him on injured reserve, coach Jason Garrett said Monday.The Cowboys are planning to run more tests on Romo's back this week, Garrett said, to give the Cowboys the most up-to-date information possible so they can make a final call over the next 48 hours.Garrett said he doesn't believe there is any deadline for the Cowboys to make a final decision on Romo."We can take the next couple of days and the reason why we want to take the next couple of days is we want to make sure it's enough time out from the original injury," Garrett said.
